8.0 MANAGEMENT OF TRADE WASTES

8.1 Council’s Objectives

The Council’s objectives are:

(a) That where public sewers are available, permitted trade wastes, and conditional trade wastes subject to certain conditions, may be discharged to the sewerage system, provided that;

(i) If the sewerage system is of insufficient capacity, the Council may refuse to allow a discharge or may grant a consent to discharge subject to conditions.

(ii) The Council may determine to grant consent to discharge trade wastes and any conditions imposed on such consent having regard to the effects of the discharge on the waste water system and receiving environment, and the effects on absolute concentrations and/or mass loadings at the point of discharge.

(iii) The Council will not approve any application for a consent to discharge trade waste if the discharge contains, or is likely to contain, a characteristic which is prohibited, except where the Council is satisfied the prohibited characteristic can be treated adequately to avoid any adverse effects on the sewerage system, the receiving environment, and people and animals.

8.2 Classification of Trade Waste Discharges

For the purposes of this bylaw, discharges of trade waste are classified as either:

(a) Permitted; or

(b) Conditional; or

(c) Prohibited

8.3 Storage, Transport, Handling and Use of Hazardous or Harmful Materials

(a) Every occupier of trade premises commits an offence against this bylaw who, without authorisation in accordance with this bylaw, by any act or omission, causes or allows the entry into the sewer system of any hazardous substance or any:

(i) matter containing corrosive, toxic, biocidal, radioactive, flammable or explosive materials; or

(ii) matter likely to generate toxic, flammable, explosive or corrosive substances in quantities likely to be hazardous when mixed with waste water; or

(iii) matter likely to be injurious to the health and safety of the Council’s staff, contractors or the public; or

(iv) matter likely to be harmful to the sewerage system


January 2009 of 37

(b) Every contractor, employee and agent of every occupier on trade premises commits an offence who, without authorisation in accordance with this bylaw, causes the entry into the sewer system of any hazardous substance or any:

(i) matter containing corrosive, toxic, biocidal, radioactive, flammable or explosive materials; or

(v) matter likely to generate toxic, flammable, explosive or corrosive substances in quantities likely to be hazardous when mixed with waste water; or

(vi) matter likely to be injurious to the health and safety of the Council’s staff, contractors or the public; or

(vii) matter likely to be harmful to the sewerage system

(c) No person may store, transport, handle or use, or cause to be stored, transported, handled or used any hazardous substance, or any matter listed in bylaw 8.3(a)(i-iv), in a manner that may allow that matter to enter the sewerage system and cause any harmful effect to the sewerage system or the receiving environment, or people and animals.

(d) This bylaw applies in addition to the provisions of the Hazardous Substances and New Organisms Act 1996 and the Resource Management Act 1991

10.15 Flow Metering

10.15.1

The Council may require the flow of a discharge to be metered when:

(a) there is no relationship between a metered water supply to the premises, and the discharge of trade waste; or

(b) the Council declines to approve a method of flow estimation; or

(c) that discharge represents a significant proportion of the total flow or load discharged to the sewerage system.

10.15.2

The consent holder is responsible for the supply, installation, reading and maintenance of any meter or other device the Council considers necessary for the measurement of the rate or quantity of discharge.

Any meter or other device installed to measure the rate or quantity of discharge is subject to the Council’s approval, but remains the property of the consent holder.

A meter must be accurate to within 10%, with no greater deviation from the previous meter calibration than 5%. Independent certification of each calibration result must be submitted to Council within 20 working days of installation, and annually within 20 working days of the anniversary of the installation date.

Where any meter is found to be inaccurate by more than 10% the Council may adjust any fees or charges to take account of that inaccuracy. Such adjustments to fees or charges may be back-dated for such period not exceeding 12 months as the Council considers appropriate.


of 37 30 June 2009

10.16 Estimating discharge

10.16.1

The Council may determine the installation of flow metering equipment is unnecessary and may instead impose fees or charges by estimating the rate or quantity of discharge as a proportion of the water supplied to premises or on any other such basis it considers appropriate.

10.16.2

If a meter is out of repair or ceases to register, or is removed, the Council may estimate the discharge. Such estimate may be based on previous readings and any other relevant information including seasonal variation. The consent holder must pay the fees and charges determined by the Council according to such estimate.

10.16.3

If the Council considers a meter has been tampered with, it may declare the reading void and charge fees according to its reasonable estimate of discharge, without prejudice to other remedies available.

10.17 Sampling and analysis

10.17.1

The Council may require the consent holder to undertake or allow sampling, testing and monitoring of any discharge to determine:

(a) compliance with this bylaw; or

(b) classification of the trade waste discharged as permitted, conditional, or prohibited; or

(c) fees or charges applicable.

10.17.2

The taking, preservation, transportation and analysis of any sample must be undertaken by an authorised officer or agent of the Council, or by the consent holder in accordance with accepted industry standard methods, or by a method specifically approved by the Council. The consent holder or person responsible for the discharge must meet all reasonable costs of sampling. Where a dispute arises as to the validity of the methods or procedures used for sampling or analysis, the dispute may be submitted to a mutually agreed independent arbitrator at the cost of the consent holder or person responsible for the discharge.

10.18 Monitoring

10.18.1 Monitoring for Compliance

The Council may monitor and audit any discharge as follows:

(a) The Council may cause a sample of a discharge to be taken and analysed in an approved laboratory by agreed or approved methods; or

(b) The Council may audit the sampling and analysis carried out by or on behalf of a consent holder; or

(c) The Council may audit compliance with consent conditions including any management plan.

All costs of monitoring and audit must be met by the consent holder or the person responsible for the discharge.

(a) One portion is to be retained by the consent holder; and

(b) A second portion is to be analysed at a laboratory approved by the Council; and

(c) A third portion is to be retained by the Council for 20 working days, and may be used for additional analysis if required.

The Council must have regard to any changes that could occur in retained samples, and those responsible for retained samples must adopt appropriate methods to mitigate against such changes where practicable.

All samples must be preserved, handled, transported and delivered to an approved laboratory according to best possible practice and approved standards.

10.19 Tankered Trade Wastes

SCHEDULE 3A: PERMITTED DISCHARGE CHARACTERISTICS

Introduction

The nature and levels of the Characteristics of any Trade Waste discharged to the Council Sewerage System shall at all times comply with the following requirements, except where the nature and levels of such Characteristics are varied by the Council as part of a Consent to discharge a Trade Waste. If a discharge Characteristic is not specifically mentioned in this Schedule and it is not referred to in Schedule 3C it may be the subject of a Conditional Trade Waste Consent

Contaminant Limit

Flow The 24 hour flow must be less than 5m3

Maximum instantaneous flow rate must be less than 2.0 L/s

Temperature must not exceed 40 oC

Solids Maximum dimension of non-faecal gross solids must not exceed 15 mm.

Fibrous, woven, or sheet film or any other materials which may adversely interfere with the free flow of sewage in the drainage system or treatment plant must not be present.

The maximum concentration of suspended solids of any trade waste must not exceed 600 g/m3.

The settleable solids content of any trade waste must not exceed 50mL/L.

The total dissolved solids concentration in any trade waste is subject to the approval of the Council having regard to the volume of the waste to be discharged, and the suitability of the sewerage system and the treatment plant to accept such waste.

Oil and grease There must be no free or floating layer.

Fat, oil or grease of other than animal or vegetable origin must not exceed 200 g/m3.

Fat, oil or grease of animal or vegetable origin must not exceed 500 g/m3.

No fat, oil or grease may be discharged that contains substances that become viscous between 0°C and 65°C

Solvents and other organic liquids

There must not be a free layer (whether floating or settled) of solvents or organic liquids.

Emulsions of paint, latex, adhesive, rubber, plastic

Emulsions may be discharged into the Sewer provided the total suspended solids do not exceed 600 g/m3. Higher concentrations may only be discharged with Council’s approval.

The Council may determine that emulsions must be pre-treated if it considers that trade waste containing emulsions unreasonably interferes with the operation of the Council treatment plant, for example by reducing the percentage of UVT (ultra violet transmission).

Emulsions, of both treatable and non-treatable types, may be discharged to the Sewer only at a concentration and pH range that avoids coagulation and blockage at the mixing zone in the public Sewer.

Radioactivity Radioactivity levels must not exceed National Radiation Laboratory Guidelines.


of 37 30 June 2009

Contaminant Limit

Colour Waste must not have colour or colouring substance that causes the discharge to be coloured to the extent that it impairs wastewater treatment processes or breaches the Council’s resource consent to discharge sewage.

pH value The pH must not be less than 6.0 or greater than 9.0.

Organic strength The Council may restrict the permitted level of Biochemical Oxygen Demand (BOD5) of any waste where the capacity for receiving and treating BOD5 is limited. A BOD5 restriction may be related to mass limits.

Where there is no Council treatment system for organic removal the BOD5 must not exceed 1000g/m3, except that this limit may be reduced to 600g/ m3 at the Council’s discretion.

Maximum concentrations

The maximum acceptable concentrations of chemical characteristics of a conditional discharge are set out in 3A.2, 3A.2 and 3A.3.

SCHEDULE 3B CONDITIONAL DISCHARGES

CONDITIONAL TRADE WASTE means trade waste that has, or is likely to have, characteristics which exceed any of the characteristics defined in Schedule 3A, but which is not defined as prohibited trade waste. Consent is required and conditions of consent may be imposed by the Council. These consents are referred to as ‘conditional trade waste consents’.

A conditional trade waste consent may impose controls on a trade waste discharge by specifying mass limits for any characteristic.

Mass limits may be imposed for any characteristic. Any characteristic of a discharge for which a a mass limit is imposed shall also have a daily maximum concentration not exceeding the value scheduled in schedule 3A, where one is given, unless approved otherwise.


of 37 30 June 2009

Schedule 3C: PROHIBITED TRADE WASTES

Prohibited Characteristics
